How Would You Know If Someone Has Blocked You Or Deleted You From Their Friends List? I Was Just Curious About That. Can Somebody Clear That Up For Me, Please? Thank You In Advance!
As far as blocking goes - the easiest way is to send a short test-PM. If it doesn't go through (ie. "Your message cannot be delivered" etc) - they've blocked you.
Re being deleted from a friend list - just go to their profile page. If you don't see the 'send online message' function open to you, and instead it says 'Ask XYZ to be a friend' - that means they've deleted you from their list, assuming you were actually on their list at some point.
